thinking about doing a new version of “plastic garbage”

I’m thinking of doing a new version of my plastic garbage work directly in location, as I’m in the van along the south coast of Portugal, I would like to photograph some of the plastic found on the beach.
I’m thinking of shooting inside the van, using natural light from the window on the roof.
I’m still wondering if I should use a white background, a black one or may be as in this first test, use a piece of plastic found on the beach as background as well.
I’m still testing, but I love the idea of having a small studio in the van.
